Privacy Policy

The short version: your numbers never leave your device. All calculation runs in your browser. We do not have a server that receives, stores, or processes the rise, run, or any other value you type in.

Calculation data

Every number you enter — rise, run, angle, pitch — is processed entirely in your browser via plain JavaScript. Nothing is transmitted to a server, nothing is stored, and no account is required. Closing or refreshing the tab discards everything. The tool is a static web page with no backend.

Analytics

We use Google Analytics 4 to understand aggregate usage (page views, tool interactions). Analytics is configured with IP anonymization. We do not send your inputs or results to analytics. Analytics may set cookies; you can block them via your browser or a content blocker.

Advertising

This site displays ads via Google AdSense (auto ads only — no manual ad slots). Google and its partners may use cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalized advertising via Google Ads Settings. In the European Economic Area and UK, ad storage is denied by default until you consent.

What we do not do

• We do not upload, store, or transmit the numbers you enter.
• We do not require an account or collect names/emails (except if you email us directly).
• We do not sell data.
• We do not use your inputs to train any model.

Children

This site is not directed at children under 13 and we do not knowingly collect their data.
